I’m working on a layout that contains a grid like layout within it to show off a set of offers. Here’s what I’m trying to achieve:

My problem is I cannot seem to get even and flushed gutters within this grid. Here’s what I have so far:

HTML:
<div id="main">
<div><img src="images/welcomeBanner.jpg"></div>
<div class="offers">
<img class="offer" src="images/offer1.jpg">
<img class="offer" src="images/offer2.jpg">
<img class="offer" src="images/offerX.jpg">
<img class="offer" src="images/offerX.jpg">
<img class="offer" src="images/offerX.jpg">
<img class="offer" src="images/offerX.jpg">
</div>
</div>
CSS:
div#content div#main div.offers img.offer{ padding-top:20px; padding-right: 20px; }
I am using padding-right:20px; on each of these offer items (img.offer). Since these offers are all inline, I cannot seem to get each row to flush with the right side of this main column (align with the right side of the larger banner with the hands).
I would love to achieve this with pure CSS, but I’m coming to the realization that might not happen. I would try :nth-child(3n), but the lack of IE support is a deal breaker for me.
I have no means of using a server side processor to do some math on the number of grid items. I recognize that I may just want to use javascript or jquery to do this math, but I wanted to reach out to see if anyone had any other suggestions.
TLDR: Help me get even gutters and a full width grid.
Thanks everyone!
I don’t know what the width of your container is, but this may help:
If you don’t want to use
nth-child()you can alternatively give every 3rd image (.offer) an additional class.
